A future artificial retina that can restore high acuity vision in blind people will rely on the
capability to both read (observe) and write (control) the spiking activity of neurons using an …

Background: Innovations in engineering and neuroscience have enabled the development
of sophisticated visual prosthetic devices. In clinical trials, these devices have provided …

Introduction Retinal implants have now been approved and commercially available for
certain clinical populations for over 5 years, with hundreds of individuals implanted, scores …

Visual neuroprosthesis, that provide electrical stimulation along several sites of the human
visual system, constitute a potential tool for vision restoration for the blind. Scientific and …

Retinal prostheses have shown some clinical success in patients with retinitis pigmentosa
and age-related macular degeneration. However, even after the implantation of a retinal …

Visual performance depends on polar angle, even when eccentricity is held constant; on
many psychophysical tasks observers perform best when stimuli are presented on the …

We present a computational-observer model of the human spatial contrast-sensitivity
function based on the Image Systems Engineering Toolbox for Biology (ISETBio) simulation …

The visual message conveyed by a retinal ganglion cell (RGC) is often summarized by its
spatial receptive field, but in principle also depends on the responses of other RGCs and …

Objective. Retinal prostheses are promising devices to restore vision for patients with severe
age-related macular degeneration or retinitis pigmentosa disease. The visual processing …

Purpose: Visual prosthetics are a promising assistive technology for vision loss, yet research
often overlooks the human aspects of this technology. While previous studies focus on the …
